If some white spots are found in the nails, it may mean that a lack of blood, and human bodies are unable to maintain normal peripheral microcirculation, which can be considered the performance of the kidney because the blood supply is reduced.
In particular, we need to focus on the hand, foot and little finger, little finger corresponds to the kidney, pale color with white patches in little fingers may prompt kidney deficiency which is often ignored.
According to the research announced earlier this year by World Health Organization, in 80% of the kidney deficiency cases white spots on the nails will be found in the early stage.
